To quickly assess the difficulty of the text, read a short excerpt:
These seams of coal are thin, not exceeding one inch, yet sufficiently numerous to have induced Mr. Hitchcock, in his minute and admirable paper for the period in which it was drawn up, (1822, ) to name it the coal formation, a term which invites a great deal of investigation, on account of the great value of the results connected with it. I would remark here, that the occurrence of seams of bituminous coal by no means identifies the rocks in which they are found with the regular coal measures,... since, without speaking of other portions of the geological column, it is stated by Professor Puschf that seams of coal from three to twenty-five inches thick are found in Poland between the muschelkalk and the oolitic series, in the very group now un der consideration a circumstance which strengthens the anal ogy between this group in Europe and the coal formation of Connecticut. To this may be added the important fact of the presence of copper in both formations, which, although exist ing under different conditions in each of them, may have been produced in each by the same cause.
